TECHNICAL FIELD

The present disclosure relates to wearable camera systems including a camera attached to eyewear, and more particularly to apparatus and methods for visualizing an approximation of an image captured by the camera and/or providing an indication of alignment of the camera.

BACKGROUND

Typically, digital cameras include a display such that the user may view an image captured by the camera prior to or after the capture of the image. The display is typically built into the camera. However, this may not be practical in some cases, for example in camera systems which are miniaturized and/or which are attached to wearable articles in a manner in which a display may not be viewable when the camera is in use. For some digital camera systems, the display may be provided on a remote electronic device, for example a handheld computing device (e.g., a smart phone) or a wearable electronic device (e.g., a smart watch). These types of camera systems would typically require wireless communication capability and often may result in higher power usage and/or higher processing capability then may be practical or desirable in some instance. Improvements to wearable camera systems may be desirable.

SUMMARY

The present disclosure relates to wearable camera systems which may include a camera (also referred to herein as eyewear camera) attached to eyewear and which may further include an apparatus for providing an indication of alignment of the camera and/or visualizing an approximation of an image or an approximation of a center of the image to be captured by the camera.

A wearable camera system according to sonic examples herein may include an eyewear which includes a temple and a lens. The wearable camera system may further include a camera coupled to the eyewear, the camera having a field of view. The wearable camera system may also include a marker coupled to the eyewear, the camera, or both. The marker may be positioned on or in front of the lens of the eyewear at a location such that when a wearer of the eyewear aligns the marker with a target, the field of view of the camera includes the target.

A method for capturing a digital image according to some examples herein may include positioning a marker on or in front of a lens of eyewear, a camera being coupled to the eyewear, aligning the marker with a target, and capturing an image with the camera while maintaining the target in alignment with the marker to include the target in the image.

DETAILED DESCRIPTION

Certain details are set forth below to provide a sufficient understanding of embodiments of the present disclosure. However, it will be appreciated by those skilled in the art that some embodiments may not include all details described. In some instances, well-known structures, eyewear and/or camera components, circuits, and controls, have not been shown in order to avoid unnecessarily obscuring the described embodiments of the present disclosure.

Examples of wearable camera systems which include eyewear and a camera coupled to eyewear are described. Systems according to the examples herein may include a marker which may be coupled to the camera, the eyewear, or both. The marker may be positioned on or in front of the lens of the eyewear at a location such that when a wearer of the eyewear aligns the marker with a target, the field of view of the camera includes the target. The marker may be incorporated into an apparatus which is configured to provide an indication of alignment of the camera and/or a visual approximation of an image or an approximation of a center of the image to be captured by the camera. Positioning the marker on or in front of the lens may include positioning the marker in contact with a lens surface (e.g., an optically transparent surface of the lens) or adjacent to a lens surface. For example, the phrase in front of the lens may generally include in front of or adjacent to any lens surface including the inner lens surface (e.g., surface near wearer's eye when the eyewear is worn) or the outer lens surface (e.g., surface opposite the inner lens surface). In some examples, positioning the marker on or in front of the lens may include positioning the marker in optical alignment with a portion of the lens.

FIG. 1 is a view of a wearable camera system 100 according to some examples of the present disclosure. The system 100 includes eyewear 105, camera 132 movably coupled to the eyewear 105, and an apparatus 120, which may include a marker 121 as will be described herein. The eyewear 105 includes an eyewear frame 110 which includes a temple 112. Typically, an eyewear frame 110 includes a pair of temples 112 (e.g., left and right temples one for each side of a wearer's head. In some examples, the temples 112 are pivotably coupled to a lens portion 117 of the frame via a hinge 113. In some examples the temples 112 are integral with the lens portion and/or hinged relative to the lens portion via a living hinge. The lens portion 117 may include a pair of lenses 102, for example and without limitation prescription lenses, non-prescription lenses, tinted lenses, changeable tint lenses, variable focus lenses, switchable focus lenses, or any combinations thereof. The lens portion 117 may include a rim 104, as in the example in FIG. 1. In some examples, the lens portion 117 may rimless or at least partially rimless. The apparatus 120, and marker 121 included therein, may be coupled to the eyewear 105, to the camera 132, or both. The marker may be positioned on or in front of the lens of the eyewear at a location such that when a wearer of the eyewear aligns the marker with a target, the field of view of the camera includes the target.

The camera 132 may be a miniaturized self-contained electronic camera system. The camera 132 may be movably coupled to the temple 112. For example, the system 100 may include an attachment system 134 configured to movably attach the camera 132 to the temple 112. The camera 132 may be slidably and/or removably attached to either of the left temple or the right temple. In some examples, the attachment system may include one or more guides in accordance with examples described in U.S. patent application Ser. No. 14/816,995 entitled “WEARABLE CAMERA SYSTEMS AND APPARATUS AND METHOD FOR ATTACHING CAMERA SYSTEMS OR OTHER ELECTRONIC DEVICES TO WEARABLE ARTICLES, incorporated herein by reference in its entirety for any purpose, for coupling the camera 132 to the temple 112.

In some example, the camera 132 may be devoid of a display. The apparatus 120 may be an image framing apparatus, which may enable the user (e.g., wearer of the eyewear) to perceive an approximate image of the image to be captured by the camera 132. The apparatus 120 (e.g., image framing apparatus) may provide a mechanism for visualizing an approximation of an image to be captured by the camera 132. The image framing apparatus may be a passive device in that it does not require the use of power and/or electrical coupling to the camera. In this regard, the image framing apparatus may also be referred to as passive view finder apparatus or simply a passive view finder. In some examples, the apparatus 120 may be electrically and/or mechanically decoupled from the camera 132. By electrically decoupled, it is generally implied that the apparatus 120 may not be communicatively (e.g., wirelessly) coupled to the camera 132.

In some examples, the camera may be removed from the lens. The camera may be in a location that is different from the location of the marker. The camera may remain in one location, which may be a location in which the camera is not optically aligned with any portion of the lens, while the marker is positioned in the location for targeting the object (e.g., a location such that when the wearer of the eyewear aligns the marker with a target, the field of view of the camera includes the target). The marker and the camera may be separate components and may be in two different locations during use. In some examples, the camera may not be optically aligned with any portion of the lens but may instead be adjacent to the lens by virtue of being coupled to a temple of the eyewear. In some examples, the camera may be separated from the marker and/or the lens, e.g., it may not be part of the lens and/or the marker.

The cameras 132 according to the present disclosure may be a miniaturized self-contained electronic device. The camera 132 may have a length of about 8 mm to about 50 mm. In some examples, the camera 132 may have a length from about 12 mm to about 45 mm. In some examples, the camera 132 may have a length not exceeding 30 mm. In some examples the camera 132 may be about 12 mm long. The camera 132 may have a width of about 6 mm to about 12 mm. In some examples, the camera 132 may be about 8 mm wide. In some example, the camera 132 may have a width not exceeding about 10 mm. In some example, the camera 132 may have a height of about 6 mm to about 12 mm. In some examples, the camera 132 may be about 8 mm high. In some examples, the camera 132 may have a height not exceeding about 10 mm. In some examples, the camera 132 may weigh from about 5 grams to about 10 grams. In some examples the camera 132 may weigh be about 7 grams or less. In some examples, the camera 132 may have a volume of about 6,000 cubic millimeters or less. In some examples, the camera 132 may have a volume of about 3,000 cubic millimeters or less. In some examples, the camera 132 may have a volume of about 2,000 cubic millimeters or less. In some examples, the camera 132 may be a waterproof camera. In some examples, the camera 132 can be water resistant. In some examples, the camera 132 can be sweat resistant.

FIG. 2 is a partial view of a system according to sonic examples herein. The system 200 may include one or more of the components of system 100 described with reference to FIG. 1. Accordingly, similar components may be indicated with like number where the first numeral of the reference number corresponds to the figure number, for example camera 232 may be similar to camera 132 and include one or more of the components of functionality of camera 132 the description of which may not be repeated in the interest of brevity and conciseness of the disclosure.

The system 200 may include an eyewear 205 and camera 232. The eyewear 205 may include an eyewear frame 210, which includes a temple and a lens portion 217. The eyewear 205 may include a lens 205 in the lens portion 217. The camera 232 may be movably coupled to the temple of eyewear 205. In some examples, the camera 232 is slidably coupled to the temple (not shown in FIG. 2) such that the camera 232 may be translated along a length of the temple, e.g., between a first or forward position to a second of aft position. In the forward position, e.g., as illustrated in FIG. 2, a forward portion of the camera 232 may be aligned or substantially aligned with a forward portion of the eyewear frame 210. In some examples, the camera 232 may be slightly ahead of the forward portion of the eyewear frame 210 when the camera 232 is in the forward position. The camera 232 may be positionable to a second position, which may correspond to a location along the length of the temple in which the camera 232 is substantially concealed from view. In the second position, the camera 232 may be substantially concealed behind an ear of the wearer. In some examples, the attachment system may be configured such that the camera 232 is movable to a position near a curved portion of the temple such that the camera 232 is positionable adjacent to or behind an ear of the wearer. In the second position, the camera 232 may be substantially concealed behind an ear of the wearer.

The wearable camera system 200 may be configured to capture a landscape image, a portrait image, or both. In some examples, the camera 232 may be pivotably coupled to the temple, for example via a hinge joint 211 or other type of pivotal joint, such that the camera 232 may be rotated between a first orientation 201 and a second orientation 203. The camera 232 may be pivotable about an axis of the temple. In some examples, the camera 232 may be pivotable between a first orientation, which may be an orientation in which the camera is adjacent to the outside side of the temple, and a second orientation, which may be an orientation in which the camera is adjacent to another side of the temple, for example a top or a bottom side of the temple. The camera 232 may be configured to capture a landscape image in one or the first or second orientation and capture a portrait image in the other one of the first or second orientation. It will be appreciated that the camera may be coupled to any side of the temple and pivotable to position the camera in any orientation with respect to the temple thereby changing a rotation angle of the image capture device with respect to a scene to be captured.

The camera 232 according to the present disclosure may be a miniaturized self-contained electronic device and may have one or more of the features of any of the cameras described herein. The camera may have a field of view. In some examples, the camera 232 may include a targeting apparatus 236 which may be positioned proximate to a camera lens 233. The targeting apparatus 236 may be configured to provide an indication of whether a targeted object (or simply target) is within or outside of the field of view of the camera and correspondingly whether the targeted object will be included in an image captured by the camera. The targeting apparatus may be implemented as a laser pointer 238 (e.g., a laser diode), which may be positioned along a side of the camera, e.g., adjacent to a top, a side, or a bottom of the camera. In some examples, the targeting apparatus may be incorporated into the camera body, e.g., enclosed or partially enclosed within a housing of the camera. The beam of the laser pointer may be generally parallel to the line of sight of the camera and may provide an indication of an approximate center of an image to be captured by the camera. In this manner, the targeting apparatus may provide a visual confirmation to the user of whether a desired object will be included in an image captured by the camera.

In some examples, the system 200 may include an image framing apparatus 220 and the image framing apparatus 220 may include the marker 221 (see FIG. 3). The image framing apparatus 220 may be removably coupled to the eyewear 205. The image framing apparatus 220 may include a view finder window 252 which is configured to provide an approximation of an image to be captured by the camera 232. During use, the image framing apparatus 220 may be positioned onto or adjacent to the lens 202 of the eyewear such that the wearer (interchangeably referred to as user herein) may view a scene through the view finder window 252 to perceive an approximation of the scene to be captured by camera 232. To the user, the view finder window 252 may be perceived as a visual disturbance or visual interference within a field of view of the user to provide an indication of an approximate boundary of an image to be captured by the camera. In this manner, a user may be able to approximately frame and thereby reduce the amount of post processing of the image (e.g., cropping the image) even in the absence of view finder on the camera itself or on a remote electronic device communicatively coupled to the camera.

The image framing apparatus 220 may include a body 251 which includes a rigid portion 254. The view finder window may be defined by the rigid portion 254. The view finder window may be implemented as a physical aperture (e.g., an opening) in the rigid portion 254. In some examples, as will be further described, the view finder window may be implemented using an optically transparent material.

The body 251 may include one or more stretchable portions 256 and one or more attachment portions 258, configured to movably couple the image framing apparatus 220 to the eyewear 205. In this example, the attachment portions 258 are implemented as hooks which are shaped to fit around respective edges of the rim to secure the image framing apparatus 220 to the eyewear 205. The stretchable portions 256 may be formed of a stretchable plastic material such as rubber, silicon, or any other suitable elastomer. The stretchable portions 256 may be sufficiently stretchable to bias the hooks towards the eyewear frame while enabling the image framing apparatus to be movable (e.g., slidable) along a first direction (e.g., a horizontal direction 242) for aligning of the view finder window with the line of sight of the wearer. The rigid portion 254 may be movably coupled to the stretchable portions 256 such that the view finder window may be adjusted in a second direction (e.g., a vertical direction 244) for further alignment of the view finder window with the line of sight of the wearer.

As described, the view finder window 252 may be configured to enable the user to perceive an approximation of an image to be captured. The view finder window 252 may include at least one image frame outline. In some examples and as shown in FIGS. 3 and 4A, the view finder window 252 may include a first image frame outline 253 which may correspond to a landscape image frame. In this manner, the view finder window and more specifically the first image frame outline 253 may enable the user to visualize an approximation of a landscape image 260 as may be captured by camera 232, for example when the camera is provided in the appropriate orientation for capturing a landscape image such as the first orientation. In some examples, the view finder window may include a second image frame outline 255 which may correspond to a portrait image frame thereby enabling the user to visualize an approximation of a portrait image 262 as may be captured by camera 232 when the camera is provided in the appropriate orientation for capturing a portrait image such as the second orientation. In some examples, one of the image frame outlines may be enclosed within the other image frame outline. In the example in FIG. 3, an image frame outline corresponding to a portrait image frame is enclosed by an image frame outline corresponding to a landscape image. In other examples, the image frame outline corresponding to a landscape image frame may be enclosed by an image frame outline corresponding to a portrait image.

In some example, the view finder window 252 may include an image center indicator 257. The image center indicator 257 may enable the user to perceive an approximation of the center of the image to be captured. The image center indicator 257 may facilitate alignment of the image framing apparatus with the user's line of sight, for example by enabling alignment of the view finder window with a pupil of the user's eye. In some examples, the image center indicator may be centered within an image frame outline of the view finder window 252. In some examples the stretchable portion 256 may be implemented as a single strip of optically transparent flexible material (e.g., silicon or clear vinyl) that spans between the attachment portions 258. The rigid portion 254 may be slidably coupled to the stretchable portion 256. The view finder window 252 may be implemented as an opening formed in the rigid portion 254 such that a portion of the flexible material is visible through the opening. The shape of the opening may define the first image frame outline, for example an image frame outline corresponding to a landscape image frame. Vertical lines may be imprinted onto the flexible material, which vertical lines as viewed through the opening may define the second image frame outline, for example an image frame outline corresponding to a portrait image frame. In some examples, the image center indicator 257 may function as the marker 221, in that the image center indicator 257 may be positionable (e.g., by virtue of adjustability of the view finder window 252) to a location such that when the image center indicator 257 with a target, the field of view of the camera includes the target.

In some examples, the view finder window 252 may not include an image center indicator 257. In such example, the view finder window 252 may itself function as the marker. For example, view finder window 252 may be positioned on or in front of the lens at a location such that when the user aligns the view finder window 252 with a target, the field of view of the camera includes the target and the target may thereby be included in an image captured by the camera 232.

In some examples, the image framing apparatus 220 may be tethered to the camera 232, e.g., via a cord, a string, an elastic, or other suitable mechanical connector. In some examples, the camera 232 may include a storage compartment, for example on a bottom, a top, or a side portion of the camera, such that the image capture device 220 may be stowed therein when not in use.

FIG. 5 is a partial view of a system according to further examples herein. The system 500 may include one or more of the components of system 200 described with reference to FIG. 2. As previously noted, similar components may be indicated with like number where the first numeral of the reference number corresponds to the figure number. For example, system 500 may include a camera 532, which may be pivotably coupled to eyewear frame 510, e.g., via a pivot joint 511. The camera may include a targeting apparatus, such as a laser pointer 538. The system 500 may include an image framing apparatus 520, which may include a rigid portion 554, one or more attachment portions 558, and one or more stretchable portions 556 spanning between the attachment portions.

The image framing apparatus 520 may include a view finder window 552 which may be provided in the rigid portion 554. The view finder window 552 may include a marker within the view finder window. In some examples, the view finder window 552 may function as a marker as described herein. The rigid portion 554 may be movably coupled to the stretchable portion 556. In this example, the stretchable portion 556 may be implemented in the form of stretchable rails 564 which may be made of a rubber or other elastomeric material. The rails 564 may be spaced apart from one another by a distance of at least a width of the view finder window 552. The rigid portion may include features for slidably securing the rigid portion to the rails 564 to enable movement of the rigid portion along the direction 244. The image framing apparatus 520 may be movable along the direction 242, for example via the attachment portion 558 (e.g., hooks) provided at each end of the stretchable portion 556.

FIG. 6 is a view of an image framing apparatus 620 which includes a marker 621 according to the present disclosure. The image framing apparatus 620 may include a view finder window 652, which may be implemented according to any of the examples herein. In sonic examples, the view tinder window 652 may function as the marker, In some examples, the view finder window 652 may include an image center indicator 657 which may function as the marker 621. In some example, the image framing apparatus 620 may include one or more image frame outlines 653, 655 and any of the image frame outlines may function as the marker.

The image framing apparatus 620 may be configured to be removably attached to the lens of eyewear, for example to lens 102 or eyewear 105 in FIG. 1. The image framing apparatus 620 may be implemented in the form of a removable decal. The image framing apparatus 620 may comprise a sheet 671 of flexible material configured to attach to a lens of the eyewear via static electrical force (also known as static cling). The sheet 671 may be made from vinyl or any other suitable flexible plastic material as is known in the art of cling materials. The sheet 671 may include an optically transparent portion, which defines the view finder window 622. The image framing apparatus 620 may include a peripheral portion 672. In some examples, the peripheral portion 672 may be made of opaque material and may be interchangeably referred to as a masking portion.

The view finder window 622 may include at least one image frame outline. In the example in FIG. 6, the view finder window 622 includes a first image frame outline 653 and a second image frame outline 655 that provide approximations of a landscape image and a portrait image, respectively, to be captured by a camera according to the examples herein. The image framing apparatus 620 may have a shape which is selected to fit within the shape of the lens of an eyewear (e.g., eyewear 105). The image framing apparatus 620 may be of any shape or size that is sufficient to accommodate the view finder window 622. In other words, the image framing apparatus 620 may be the size of or substantially the size of the view tinder window 622 and may not include any peripheral portion. In some examples, the image framing apparatus 620 may be larger than the size of the view finder window, for example to provide additional plastic cling material for increased adhesion to the lens. The image framing apparatus 620 in the form of a decal may be affixed to and removed from the lens multiple times as may be desired for alignment and/or use of the image framing apparatus.

In some examples, the marker may be movably or removably attached to the camera. FIGS. 7-8 illustrate examples of apparatuses which include a marker movably attached to a camera according to the present disclosure. FIG. 9 illustrates examples of apparatuses which include a marker configured to be removably attached to a camera.

FIGS. 7A and 7B illustrate bottom views a wearable camera system 700 according to further examples of the present disclosure. The system 700 may include one or more of the components of wearable camera systems described herein, for example system 100, 200, or 500 described previously with reference to FIGS. 1, 2 and 5 respectively. Accordingly, similar components may be indicated with like number where the first numeral of the reference number corresponds to the figure number, for example eyewear 705 may be similar to eyewear 105 in FIG. 1 and include one or more of the components of functionality of eyewear 105, the description of which may not be repeated in the interest of brevity and conciseness of the disclosure.

The system 700 may include eyewear 705 and eyewear camera 732. The eyewear 705 may include an eyewear frame 710 which may include a pair of temples 712. The eyewear 705 may include a pair of lenses 702, which may be, without limitation, prescription lenses, non-prescription lenses, tinted lenses, changeable tint lenses, variable focus lenses, switchable focus lenses, or any combinations thereof.

The eyewear camera 732 may be movably coupled to the eyewear 705, for example slidably coupled to temple 712 of eyewear frame 710 using an attachment system described in U.S. patent application Ser. No. 14/816,995 entitled “WEARABLE CAMERA SYSTEMS AND APPARATUS AND METHOD FOR ATTACHING CAMERA SYSTEMS OR OTHER ELECTRONIC DEVICES TO WEARABLE ARTICLES, incorporated herein by reference in its entirety for any purpose. The camera 732. may be a miniaturized self-contained electronic camera system. The camera 732 may include one or more of the components and/or functionality of any of the cameras described herein or described in U.S. patent application Ser. No. 14/816,995. The eyewear camera 732 may include a camera body 734. The camera body 734 may include an optical system 735 and any internal electronics of the eyewear camera 732. In some examples, the optical system 735 may include a camera lens and/or an image capture device, such as a charge-coupled device (CCD) image sensor. The optical system 735 may be partially of fully enclosed within a housing of the camera 732. The eyewear camera 732 may have a field of view 706. A marker 721 may be coupled to the camera 732 such that the marker 721 may be positioned on or in front of the lens of the eyewear at a location such that when a wearer of the eyewear aligns the marker 721 with a target, the field of view 706 of the camera includes the target. The target may be an object or a scene that the wearer may wish to photograph.

In some examples, the eyewear camera 732 may include an alignment indicator 737, which may be configured to provide an indication of angular orientation of the camera 732 relative to a horizontal direction (e.g., direction 845 in FIG. 8). The alignment indicator 737 may be pivotably coupled to the camera body 734 such that the alignment indicator 737 may be moved between a first position (e.g., a deployed position as shown in FIG. 7A) and a second position (e.g., a stowed position as shown in FIG. 7B).

In the deployed position, the alignment indicator 737 or a portion thereof may extend into the field of view of an eye of a wearer of the system such that the wearer may perceive the alignment indicator or a portion thereof. For example, the wearer may perceive the marker 721 when the alignment indicator is in the deployed position. The alignment indicator 737 may be configured to pivot between the deployed position, in which the marker 721 is in the field of view of the wearer, to a stowed position, in which the marker 721 is adjacent to the camera. In the deployed position, the marker 721 may be positioned on or in front of the lens of the eyewear at a location such that when the wearer aligns the marker with a target, the field of view of the camera includes the target. The alignment indicator 737 may include an arm coupling the marker 721 to the camera 732. The marker 721, which may be located at an end of the arm, may provide a visual disturbance or visual interference within the field of view of the wearer such that the wearer may be able to determine if an object he or she wishes to photograph will be captured by the camera. In the stowed position, the alignment indicator 737 may be partially or substantially outside the field of view of the eye of the wearer.

Referring now also to FIG. 8, which illustrates a front view of a system 800 according to examples of the present disclosure, additional features of alignment indicators and cameras including alignment indicators according to the present disclosure are described. The system 800 may include some or all of the components of system 700 described previously with reference to FIG. 7 or any of the systems described herein. Accordingly, similar components may be indicated with like number where the first numeral of the reference number corresponds to the figure number. For example eyewear 805 may be similar to eyewear 705 in FIG. 7 and include one or more of the components of functionality of eyewear 705, the description of which may not be repeated in the interest of brevity and conciseness of the disclosure. The system 800 may include eyewear 805 including frame 810, the frame 810 including a temple 812.

The system 800 may include a camera 832 movably attached to temple 812. The camera 832 may include an optical system 835 which may include a camera lens 833 and may be configured for capturing an image. The camera 832 may include an alignment indicator 837 which may be movably coupled to camera 832. For example, the alignment indicator 837 may be pivotably coupled to the camera 832, for example a bottom portion of the camera. The alignment indicator 837 may be pivotable from a first position, for example a deployed position, to a second position, for example a stowed position. In some examples, the alignment indicator may include an arm 839 and a center indicator 841. It will be appreciated that term center is not meant to imply a precise center of an image to be captured; rather the center indicator may be used to visualize an approximate center of an image to be captured. The center indicator 841 may be located at one end of the arm 839 while the other end of the arm 839 may be pivotably coupled to the camera body. In some examples, the center indicator 841 may be provided at an intermediate location along the length of the arm 839. In some examples, e.g., depending on a size of the camera 832 and/or eyewear 805 to which the camera is attached, the arm 839 may be collapsible or extendible. For example, the arm 839 may be implemented as a telescoping arm which may extend in length for use and collapse in length for stowage, e.g., so that the alignment indicator 837 may fit completely within a footprint defined by a size of the camera. In some examples, the alignment indicator may be coupled to the camera such that when the alignment indicator is deployed, the arm portion is in-line with a horizontal axis of the camera. In this manner, the alignment indicator may provide an indication of the horizontal alignment of the camera by essentially providing a way to visualize whether the horizontal axis of the camera is aligned with the horizontal direction 845 when the camera is worn and fully or partially outside of the field of view of the wearer. If the arm, which may function as an extension of a horizontal axis of the camera into the field of view of the user, is angled relative to the horizontal direction 845, the user may adjust the angular orientation of the camera (e.g., by pivoting the camera or a portion thereof relative to the eyewear frame). In some example, the user may correct horizontal misalignment by tilting his or her head until the arm aligns with the horizontal direction 845.

In some examples, the alignment indicator may be separate from the camera and removably attachable thereto, e.g., as will be described with reference to FIG. 9. FIG. 9 illustrates embodiments of alignment indicators according to further examples of the present disclosure. The alignment indicators 920, 920′ may be implemented in the form of a sheet 971 of flexible plastic material (e.g., static cling material) such that the alignment indicators 920, 920′ may be removably attached to the camera (e.g., camera 132), the lens (e.g., lens 102), or both. The sheet 971 or portions thereof may be optically transparent. The sheet 971 may include one or more markers 921, 921′.

The sheet 971 may have a generally rectangular shape and may include a camera portion 980, 980′ and an eyewear portion 982, 982′. In some examples, the sheet may be oval or generally oval in shape or may have an irregular shape as may be appropriate for a particular design of eyewear frame and resulting location of the camera attached thereto. For example, the sheet may have a curved shape such as a C shape or an S shape. The camera portion 980, 980′ may be sized and/or shaped to fit over a front portion of the camera and attach to the front portion of the camera via static cling. The sheet 971 may include a camera aperture 981, which may be a physical aperture (e.g., a hole in the sheet 971) or a virtual aperture defined by a portion of optically transparent material. The camera aperture 981 may be located in the camera portion 980, 980′ and may be sized to fit around or substantially around the camera lens such that an image may be captured with the camera while the sheet 971 remains affixed to the camera. The camera aperture 981 may have virtually any shape, such as rectangular, square, circular or oval shape, provided that the camera aperture 981 is sized and/or shaped so as to fall outside or substantially outside a field of view of the camera such that the camera aperture 981 does not substantially interfere with the capture of an image. In some examples, the camera aperture 981 may have a lateral dimension (e.g., a diameter or a width) which is substantially equal to or greater than a lateral dimension (e.g., a diameter) of the camera lens (e.g., camera lens 233 as in FIG. 2). The eyewear portion 982, 982′ of the sheet may extend from the camera portion 980, 980′ towards the user's field of view when the image framing apparatus is in use (e.g., attached to the wearable camera system).

The alignment indicator may include one or more markers 921, 921′. In some examples, a marker may be located in the eyewear portion 982, 982′. The eyewear portion may include a plurality of markers 921, 921′. The marker may have virtually any shape, for example a cross-hair, a bull's eye, an outline having virtually any shape such as a circle, triangle, square, or star, or any combinations thereof. Markers according to the present disclosure may facilitate alignment of the camera with a desired line of sight for capturing an image. For example, the marker may enable the user to determine whether a target (e.g., an object) would be included in a captured image and align the field of view of the camera to include the target in the captured image. In some examples, a plurality of markers may be provided for use with different settings of the camera. For example, a camera may have zoom capability and a different marker may correspond with an approximation of a center of the field of view of the camera at each of the zoom settings of the camera. In some examples, the alignment indicator may also provide the functionality of framing an image. For example, the sheet may additionally include one or more image frame outlines as described herein which may enable the user to visualize an approximation of the image to be captured. It will be further appreciated that any of the examples herein may be used in any combination with one another.

A method for capturing a digital image according to the present disclosure may include some or all of the following steps. The user may position a marker on or in front of a lens of eyewear, a camera being coupled to the eyewear. The user may aligning the marker with a target, for example an object the user wishes to capture, and the user may then capturing an image with the camera while maintaining the target in alignment with the marker such that the target is included in the image. In some example, positioning the marker may include attaching a sheet of static cling material to the lens, the sheet including the marker. The sheet may be sheet 671 or sheet 971 some or portions of which may be made from an optically transparent static cling material. The method may include repositioning the sheet by removing the sheet from the lens and reaffixing the sheet to a new location on the lens.

In some examples, the marker may be provided on a sheet of static cling material which includes a camera aperture and the positioning of the marker may include aligning the camera aperture of the sheet with the lens of the camera prior to attaching the sheet to the front portion of the camera. In some examples, the marker may be attached to an arm pivotably coupled to the camera, and the positioning of the marker may include rotating an arm from a first position (e.g., a stowed position) to a second position (e.g., a deployed position). In some examples, the camera may be movably coupled to the eyewear, for example pivotably coupled to the eyewear. The user may capture an image in a first orientation, for example a landscape orientation. The user may rotate the camera from the first orientation to a second orientation for capturing an image in the second orientation, for example a portrait orientation. In some examples, the method may include aligning a horizontal direction of the camera by rotating the camera or a front portion of the camera relative to the eyewear to align an alignment indicator with a horizontal direction (e.g., the ground).
